Identify the key instrument sensors of a semiconductor manufacturing line and model the alarm conditions for potential chip failures.
This capability would be sought out by any semiconductor manufacturer who wants to maximize their yield. Currently wafers are tested after specific process levels are completed. Much of the critical testing can’t be performed until very far along in the manufacturing process. Thus a failure early in the process will consume costly resources as the wafer continues onto other fabrication steps, only to be scrapped at the end. If statistical sampling is used then there’s also the added risk of failing chips shipping to customers. Having the ability to catch failures in almost real time during any process step minimizes the chance of failure propagation and improves isolation time of equipment issues thereby greatly improving yield and reducing costs.
The date used for ths project will be the SECOM Data Set which is publicly available from UCI archive. The dataset is comprised of 1567 observations, one observation per wafer fabricated, 591 variables corresponding to various sensors in fabrication equipment, with 104 failing observations total.
- Any variable missing more than 10% of the total observations cannot accurately contribute to a model so will be dropped from the analysis.
- Remaining missing data will be imputed.
The SECOM Data Set consists of two csv files. The first is a list of pass/fail and date/time results, one entry per lot run, and the other contains the corresponding numeric results of sensor readings from a semiconductor manufacturing line. The data files do not contain a header so variable names ‘Status’, ‘Date’, and ‘Time’ were assigned for pass = -1 / fail = +1, date and time. The ‘Status’ variable is then updated to pass = 0 / fail = +1 for convenience when fitting the data to categorical models. The remaining variables assumed default names: V1, V2, etc. Table 2.1 below shows a sampling of the initial dataset. Since the sensor variables are not named in the original dataset, and since no information is provided about the physical meaning, source or process order of each sensor’s data, there is no way to attribute any process or business meaning to the data. Therefore the analysis herein will take a “black box” approach.
| Status | Date | Time | V1 | V2 | V3 | V4 |

Sensor data comprise real valued coninuous random variables by nature. So any variable that contains only missing data or has no variation is irrelevant for this analysis and can be dropped. The approach taken here was to drop all variables where the distribution min = max. It’s not clear why these data were included in the SECOM dataset, but since the goal is to identify signals or combinations of signals leading to an alarm condition, unvarying sensor data are irrelevant. The next important issue with the dataset was to properly classify all missings as “NA”. Missing results can be defined by a number of non-standard labels including “N/A”, “missing”, “na” or even " “. The naniar package provides a simple function replace_with_na_all() to simplify converting this arbitrary list of labels to”NA“. Finally, there were a number of”NaN" designations that aren’t typically interpreted as missings, but since the sensor data should be real values it was determined these values should be treated as “NA”. It was found that initially 5.59% of the dataset was missing. While that doesn’t seem to be too significantly large, it depends on how missingness is distributed within the dataset. Among the many useful features of the naniar package are plotting routines for visually exploring missingness. One of the routines gg_miss_var() is shown below in Figure 1 in which the variables are ordered by total missingness and plotted on the y-axis, and the number of missing observations on the x-axis. The number variables in this dataset is too large for printing so are omitted from the y-axis. The notable takeaway here was that most of the missing data was limited to a relatively few number of variables. The safe approach taken was to drop all variables with > 10% missing data leaving just 1.63% total missing data for imputation.
Fig. 2.1: Visualization of initial missingness.
There are several R packages for imputing data. Initially, the simputation package was chosen for it’s ease of use and integration with naniar and ggplot2. Unfortunately, the number of variables in this dataset created multiple run-time issues for the simputation engine so it had to be abandoned. Instead, the mice package, which stands for “Multivariate Imputation by Chained Equations”, provided powerful fitting functionality at a moderate computation cost. The package is capable of fitting a different imputation model to each variable, but the norm.nob method was applied unilaterally and found to return reasonably good values on comparing pre- and post-imputation distributions. Figure 2.2 shows a sample distribution for a random variable overlaying the imputed values in the histogram. A summary of the initial imputation effort is shown in Table 2.2. Of the initial 593 total variables in the dataset, the post-wrangling count was 417. And the initial 4.51% total missing data has been reduced to zero.

An important requirement for developing a multivariate model for this project is how well the individual sensor data distributions can be modeled by a known statistical distribution type. Ideally each variable would follow the well known normal distribution. The figure below shows an example of one variable in the SECOM dataset that is roughly normal based on visual inspect of the probability density (PDF) distribution. Included below that is its corresponding Q-Q plot, or quantile plot, which plots the measured versus theoretical quantile data. For an ideal normal distribution the fit line of a Q-Q plot would be colinear with the data and have very small residuals over the entire +3/-3 z-score range. The farther the fit line deviates from data the less confident we can be that the distribution is normal. A reasonable target is that at least 95% of the data fits the distribution which corresponds to a good fit between z = -1.96 to +1.96. Since the goal of the model in this project is to predict physical wafers failures based on production sensor data, the distribution is also shown comparing passing and failing results Except for differences in the tails, there’s very little distinction between the distributions. Since it’s not known if the differences in the tail data is important or not, the apparent outliers will not be removed from the analysis yet.The second set of plots below show the data for another sensor which also follows a normal distribution, but comparison of yield results shows differences in both the peak probability and tail distribution.
Fig. 3.1: Example of near normal distributions.
Fig. 3.2: Example of near normal distributions with yield differences.
What happens then for data that do not exhibit a normal distribution? The figure below shows the case for a right-skewed distribution at the top left with corresponding Q-Q plot below it. The longer right tails is clear in the PDF plot but really stands out in the Q-Q plot where the trend sharply deviates near z = +1. For distributions like this one the plan is to transform the original data into a form that is closer to normal. The plots on the right side show the result after taking the logarithm of the sensor values. The effect is seen as rebalancing the distribution, making it more symmetric about the mean. There are many non-normal distribution types available for custom fitting these data, but the approach that will be taken here will be to apply logarithmic transform, or shift + transform. The problematic situation is when the data do not follow any single distribution type but is comprised of a superposition of two or more component distributions. The second set of plots below show examples of multi-modal sensor distributions. This data could be fit with a superposition of distributions, but review of the Q-Q plots shows that a normal distribution can describe the overall distribution adequately. In this project then, multi-modal distributions will be approximated by a normal or log-normal distribution as best fits the data.
Fig. 3.3: Example skewed distribution.
Fig. 3.4: Example multi-modal distributions.
A scatter plot is good way to assess relationships between pairs of variables. The more that the data trends with a positive slope the more the two variables are correlated. On the other hand, the more the data trends with a negative slope the more the two variables are anti-correlated. When building a model with a few variables this is a convenient way to visually identify the relevant features. The example scatter plot matrix below shows the relationships between the first ten variables in the SECOM dataset plus the dependent variable ‘Status’. To quantify the relationship between two variables a correlation analysis is run and generates a correlation coefficient between -1 and +1. Correlated data obtain a coefficient > 0 up to a maximum of 1 and anti-correlated data obtain a coefficient < 0 down to a minimum of -1. Fig 3.6 shows exampes of highly correlated (top), highly anti-correlated (bottom) and uncorrelated (middle) variable pairs in the SECOM dataset. Table 3.1 below that lists the same information in tabular format.

A correlogram is another useful visualization tool for spotting trends in variable relationships. The correlogram reduces the information in the scatter plot matrix to a color-coded matrix of correlation coefficients for easy identification of trends. The relationships for the first 10 variable plus the dependent variable are shown below in Fig. 3.7. In a dataset with hundreds of variables these visual aids aren’t very useful. Fig. 3.8 below shows the case for the current SECOM dataset. The plot does show interesting clustering trends but this amount of data is too cumbersome to perform visual analyses. The approach that will be taken in this project is to select features based on their statistical significance in a given model.
Fig. 3.7: Example correlogram plot.
Fig. 3.8: Correlogram plot for the SECOM dataset.
While the number of cross-correlations makes visual analysis cumbersome in general, it is still interesting to review how each variable is correlated to the dependent variable, ‘Status’. Fig. 3.9 plots the SECOM variables ordered by their correlation coefficient with ‘Status’. The notable takeaway is that none of the individual variables is signficantly correlated with the ouput response meaning that the final model should expect to retain a significant number of independent variables.
Fig. 3.9: Correlation coefficients for the dependent variable, Status.
The data approach taken here was to split the available data into 3 parts for initial model training (85%), model tuning (10%) and final test verification (5%). Table 4.1 below shows the breakdown of available data by number of observations and percentage of the total avaialble dataset, and the number of pass/fail observations for the datasets used here. The greater than 10:1 pass:fail delta in these datasets is notable and addressed further into the analysis.

|---|---|---|---|---|
| All Data | 1567 | 100.00 | 1463 | 104 |
| Train | 1332 | 85.00 | 1244 | 88 |

For this initial baseline model all available features are used for a logistic regression. The glm model was unable to converge consistently so the bayesglm model was chosen instead. The bayesglm model uses the Student-t distribution instead of the normal distribution which better describes the SECOM variable distributions in this work. Due to the number of available features the fitting results are lenghy so are shown in Appendix C. The model’s low AIC score of 949 indicates a parsimonious model. The confusion matrix results below show the fit accuracy = 0.9925, sensitivity (TPR) = 0.9992 and selectivity (TNR) = 0.8977. Since the purpose of the model is to accurately predict failures, TPR is a primary measure of the model capability. Overall the base training model is very good.

The area under the receiver operating characteristic (ROC) curve, or area under the curve (AUC), illustrates the diagnostic ability of a binary classifier model as its discrimination threshold is varied between 0 and 1. The curve is a plot of the true positive rate (TPR, sensitivity) against the false positive rate (1 - TNR, 1 - specificity) with the range of AUC between 0.5 and 1. A score of 0.5 corresponds to having little discernability or little predictability better than chance and is represented by a 45 degree line. A score of 1 corresponds to perfect discernability and is represented by a curve that tents to the upper lefthand corner. For this model AUC = 0.7889 and is plotted below.
Setting the threshold to 0.01 increases TNR to 0.8182, but decreases accuracy to 0.7707 and TPR to 0.7671.

In the original logistic fit many coefficients showed very little signicance, meaning their their significance values were > 0.05. In the following fit approach the logistic regression is performed iteratively with the least significant variable removed after each iteration. This assures that only the most significant features remain. Please refer to Appendix D for model output details. This approach shows a significant improvement in AIC score of 515. The accuracy = 0.9234 and TPR = 0.9855 are also very good, but TNR = 0.0455 has dropped significantly compared with the base model. Confusion matrix results and a plot of most to least significant model features are shown below.
